We're really going back to the formula that got our run game going the first few years now.
The 4 Fullbacks are:
Jalston Fowler (a Titans cut)
Tre Madden from last years team
UFA Khalid Hill
UFA Marcus Martin
Competition at the FB spot to see who's going to lead Penney and Carson.
I think Hill might stick. He played in a pro style Offense at Michigan and also played TE a little, so at around 265 lbs provides some versatility for Schottenheimer.
Combined with 2 good blocking TE's, the run game should see some improvement.
